Firefighters have issued a smoking safety reminder after a discarded cigarette is believed to have caused a roof garden fire in Craven Road in Ealing.
An external living wall was destroyed by the fire and most of the decking on the seventh floor was damaged. Part of the seventh and eighth floor corridors were also damaged. There were no reports of any injuries. Around 60 people left the building before the Brigade arrived.
The Brigade's fire investigators believe the most likely cause of the fire is due to the unsafe disposal of smoking materials, such as a cigarette or match.
A London Fire Brigade spokesperson said: "We would rather people didn’t smoke at all but if they do, vaping is a safer option.
"If you do choose to smoke cigarettes, it is absolutely vital you ensure your cigarette is completely out when you’ve finished smoking it.
"If you don’t, you risk causing a fire which could not only destroy your home, but also cost you your life."
